Oh, and I tried it again this morning, after the laptop had been off all
night, and this time it worked (live image boot). I then tried
rebooting and running the installer, and it failed in the usual place.

I'm booting using EFI.

If I plug the stick into the laptop when it's running, the stick is
mounted okay. I ran sum(1) on all the files, using "find ... -type f".
I didn't see any problems in kern.log. I poked around with cd and ls a
bit and didn't notice anything odd, but then I'm not familiar with the
contents of a hybrid image ISO.
Thanks for all your help on this.
